Seo optimization: Baidu natural ranking describes the Indexing Rule conjecture (the reason why the description is not included)

Introduction:

"Why does the search engine include website content instead of description? "

Early searches rely on descriptions, titles, and key words to determine the topic.

Currently, all search engines use full-text indexes, including descriptions and keywords.AlgorithmInstead of submitting the description.

If the description and content are consistent, it may be displayed. If the description is not consistent, the content will be displayed. When a sentence can be extracted from the body, the body content should be prioritized when describing the search keyword. If the description is not displayed, the description is used for better user experience. Presenting more authentic search content is the most relevant topic document if given priority."-- Paste

 

Recently, when I checked the website's optimization and website indexing status, Baidu and Google found that, except for the meta tag description on the homepage, none of the other pages were displayed. After the check, it is found that the text of the included description is extracted from the content of the text. Record the current phenomenon.

Website Background: 1. One is a div + CSS webpage, and the other is a table webpage.

2. The website is not a homepage. One is dynamic and the other is static.

3. Category pages and details pages.

 

Symptom:

1. Baidu's algorithms on this point change frequently. On the same page type, different snapshots are captured in different locations.

2. static text is slightly better than label description text, and text is not included in <A> and other label descriptions, between <span> <TD> </TD> <font> or directly static text, the display exposure rate is high. At least this is the current update in March.

3. The closer the text is to form or body, the closer it is to the top of HTML.

4. Relevance of the text. (We can't see much influence at present. Continue to observe .)

 

Record it first, and continue to correct and supplement it later.
